I'm a regular user, did my recent trip couple of days back. Entire stretch is well laid and not pot holes / patches, with more than sufficient restaurants & fuel stations. Only down side will be the intermittent 2 lanes from Ulundurpet to Attur. If you have fastag you could save a lot of time as well (except for Paranur toll every other toll has fastag lanes)
Thanks, roads were awesome !
Started from Chennai Annanagar at around 3:30 with traffic snarl until melmaruvathur (5 PM) and reached rasipuram by 10:30 which inclusive of 2 breaks one after Thindivanam (near Sithanni) and the other being A2B at Thulukkanur.
National Highway 79, I must say the road from Ulundrupet - Kallakurichi - Chinnasalem - Attur was simply superb and the road from Attur - Malliakarai - Rasipuram was pleasant surprise with so many Road Reflector/ Road Studs and extended wide roads making it so very suitable to drive. Seemed like both the roads were recently laid.
